First IUI tomorrow!

After two years of trying, we will be doing our first <a href="https://glowing.com/glow-fertility-program">IUI</a> tomorrow! I should mention that I have been pregnant 3 other times with no issues with fertility! Unfortunately we lost two pregnancies due to incompetent cervix but I had a surgery to correct it and have a beautiful almost 3 year old daughter! Her birthday is on the 27th! I have always been able to get pregnant right away until trying for this baby. 
What can I expect for tomorrow?! I am nervous and excited. I should also mention that my husband is not able to stay for the <a href="https://glowing.com/glow-fertility-program">IUI</a> tomorrow since he is a LT. For a fire department and he works tomorrow! So that part sucks. 
Any success stories on the first <a href="https://glowing.com/glow-fertility-program">IUI</a>? Any help would be great!
